Experience sharing of precision hardware tool stamping parts manufacturers-how to deal with material forming cracks

In recent years, the small author’s company has received precision metal tool stamping parts made of various raw materials. One product has a different appearance, and the other has a big difference in raw materials. It also encountered many problems during development. Especially for stamping parts that require heat treatment, we have also summarized our experience for reference: A few years ago, we received wrench stamping parts from customers, originally designated to use SPCC raw materials, the materials used are soft, and there is no need for forming and bending. Problem: After trying out the product, the customer found that the product was not hard enough to be fully applied to their assembly, and asked us to recommend the use of raw materials. Usually, the cold-rolled plate of No. 45 used in tool products, we also recommend this material; but when forming, This stamping part produces micro-cracks due to the strong rigidity of the material itself, and the tempering process can be used before forming; there is no problem in subsequent forming, and the customer's hardness requirements can also be met; at the same time, some customers specify to use 50# cold Rolled steel is also a material that can be quenched at high temperature. It is also very suitable for high-strength hardware tools. In the subsequent heat treatment process, some strong supply units are reserved to solve customer problems and deliver customer satisfaction products; think In addition to excellent suppliers, a wealth of experience is still needed to make products that satisfy customers, and these can usually give you a satisfactory answer.
